Application filed June 22.1906. Serial No. 322.941.

To all when it may concern:

Be it known that I, CLARENCE L. TAYLOR, of Alliance, in the county ofStark and State of Ohio, have invented certain new and usefulImprovements in Beam-Straightening Presses; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to1o make and use the same.

My invention relates to an improvement in beam-strai htening resses, theobject being4 to provi e a macliine of this character comprising arelatively fixed ram and a re f5 ci rocating ram, with means whereby there atively fixed ram may be adjusted with relation to the reciprocatingram.

A further object is to provide each ram witha movable die, combined withdevices zo whereby when one die is moved to an operative position theother will be moved to an inoperative position.

The invention consists in the parts and combinations of parts, as willbe more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in verticallongitudinal section of my improved machine. Fig. 2 is a view inhorizontal section. Fig. 3 is a view in transverse 3o vertical sectionbetween the rams. Fig. 4 is a view in rear end elevation, and Fig. 5 isa view in section through the cylinder rackbar and shaft for rotatingthe pivoted die.

1 represents a base-frame, and 2 an up- 3, 5 right frame secured to thebase-frame at the rear end of the latter. Mounted in the up right frame2 are the two shafts 4 and 5, located transversely of the machine in thesame vertical plane. The lower shaft 4 is 4o provided at one end with apinion 6, which is 1n mesh with smaller pinion 7 on shaft 8, driven by amotor 9, and suitable caring. This shaft 8 also carries the fly-whee 10.

Shaft 4 is provided on its end farthest removed from the pinion 6 withthe pinion 11, which meshes with pinion 12 on shaft 5, thus causing thetwo shafts to rotate in unison. Each shaft is provided with twoeccentrics, and a /pitman 13 is mounted on each eccentric. he fourpitmen thus mounted are pivotally connected to the rear face of thereciprocating ram' 14, which is mounted to move back and forth on thebed-plate 1, the latter being provided with guideways in which the rammoves. The adjustable ram 15 is also mounted to move in the guideways onbase 1 and is provided near its four corners with internallythreadedsleeves 16, which latter project inwardly toward the ram 14 and areengaged by the four screws 17, which latter pass rearwardly through theu right frame 2 and carry the toothed whee s 18, each of which mesheswith thelarger wheel journaled to the shaft 20, mounted in upright frame2. One of the wheels 18 is engaged by a smaller wheel 21, secured onshaft 22, journaled in bearings secured to the top of frame 2. Thisshaft 22 carries a pulley 23, which is driven by a belt 24, actuated bythe motor 25. By rotating the shaft 22 in one direction the four screws17 will be turned in a direction to move ram 15 away from ram 14, and areverse movement oftheshaft will rotate the screws in a direction tomove ram 15 toward ram 14, lengthwise movement of the shafts beingprevented in one direction by the pinions 18 bearing against the rearface of frame 2 and in the other direction by the collars 26 on thescrews bearing against the upright partition 27. The ram 14 is moved apredetermined distance toward and away from die 15 at each stroke of theeccentrics, and by means of the screws the ram 15 can be adjusted towardand away from ram 14 and set for any depth or thickness of beam.

Each ram is vertically concaved, as at 28, at the center of its inner orworking face for the reception of the dies 29. These dies are eachjournalcd at its ends in bearings in its respective ram, and each isconstructed with a rear face curved in the arc of a circle and hearingdirectly against its ram and with a ribshaped outer face, which bearsagainst the beam being straightened. Each ram 14 and 15 is also providedon its inner or working face and on opposite sides of its die with oneor a series of ribs 30.

The die of each ram is provided near its lower end with a miter-gear 31,which meshes with a similar ear 32 on sleeve 33, while the die of theadjustable ram is provided near its lower end with a miter 34, whichmeshes with a miter 35, fast on sleeve 36. The sleeves 33 and 36 areconnected with the rams 14 and 15, so as to move therewith and are bothmounted on the shaft 37, lon which they are free to slide. This shaft isl solidly mounted at its front end in the bear- IOO ing 38 and isprovided with a pinion 39 fixed thereto adjacent to said bearing.

Meshing with pinion 39 is the rack 40, which latter is actuatedpositively in both directions by the double plunger 41 in cylinders 42,the rack 40 being pivotally connected to the pitnian 43, which latter isconnected to the plunger intermediate the cylinder 42.` The dies beingthus coupled up to the shaft io 37 are turned or partly rotated inunison and are so arranged that when one die is turned to present itsrib outwardly beyond the fixed ribs on its ram, as shown in Fig. 2, theother -idie will Lbe turned out of action. If straight- 15 ening` isrequired on the otherside of beam,

i the-direction of movement oi the rack is reversed; thus turning bothdies and bringing into action the one that was formerly inactive. Thesleeves 33 and 36 are free to slide zol `on shaft 37, thus permittingthe latter to actuate the dies irrespective of the position of either orboth rams.

44 `are rollers extending longitudinally of i the `machine and throughthe rams and form 2 5 supports on which the,` beams rest while in i themachine. These rolls are actuated i through the gears 45 and 46 and theshaft 47 which latter is actuated in ,unison with a ,roller-table (notshown) placed on each side 3o of the beam-straightener.

`In, the operation of this machine the adi justable ramf` 15 should befirst adjusted to- `ward or ,away from rami 14. This adjust- ,'ment maybe made after or `before the beam. 35` ihas been run into ositionbetween the rams. Alter thei rams aveil thus been adjusted power appliedto the movable ram, through 1 theeccentric shafts 4 and 5 forces themoveable ram toward the adjustable ram and the 4o ,die bearing at oneside against the beam in a yiplane `between the fixed ribs of the otherram operates to straighten out the beam.

It is evident that many slight changes @might be resorted to in therelative arrange- `1,5rnent of parts shown and described-withoutldeparting from the spirit and scope of myinvention. i Hence I` wouldhave it understood that I do not wish to confine myself to the -exactconstruction of parts shown and described; but,

Having fully described myinvention, what I claim vas new, and desire tosecure by Letters Patent, is-
